I have used both of the counters on my PCI-6229 board. Is there any way to use the digital I/Os to generate a PWM signal? I need to change the duty cycle to control a valve. The frequency is 300Hz.
Your best best would be to do correlated digital output. This does not have the ease of use of pulse width modulation, but you would be able to specify the digital waveform you output from your board.
I have a labview block diagram and the physical equipment to generate a voltage. This voltage is then sampled by a labview program and changed to a PWM signal. The signal is then fed to another circuit to drive/control a dc motor. I have a 50 pin E series connector. How do I connect the output of the power supply to the input of the DAQ 6025E board? Which pins? How do I connect the output of the DAQ board to the input of the circuit that controls the DC motor. Which pins?
